摘要：Disclosed is a process for the preparation of aromatic hydroperoxides

comprising contacting two liquid phases comprising an oily phase containing an aromaticcompound having a secondary alkyl group and a basic aqueous phase under agitationwith a molecular oxygen-containing gas in the presence of a copper compound catalystsuch as an inorganic salt or organic acid salt of copper, thereby to oxidize the aromaticcompound to a corresponding aromatic hydroperoxide, wherein the liquid phase catalyticoxidation is carried out while maintaining the catalyst concentration in the liquid phases at0. 005 to 10 ppm as the copper atom and the pH value of the basic aqueous phase at 7.6to 10. According to this process, by adoption of the above-mentioned specific catalystconcentration and pH value in combination, the rate of oxidation of the aromaticcompound is increased and the selectivity to the hydroperoxide is improved.
